The Human GPS: How a Brain Navigates in Unfamiliar Environments, Drexel University Study

How do we navigate an unfamiliar environment? It turns out that our brains contain a type of GPS cell which allows us to keep track of our relative location. Now, scientists have identified that cell and have learned a little bit more about how we keep track of where we are. The new type of cell is called the "grid cell," so called since during navigation it activates in a triangle grid pattern. It's distinct among brain cells since its activation represents multiple spatial locations.
